Is it possible to also display with maps (Google Maps, etc) which are representing the location on a J2ME application? If so, how?

I tried some of the method from your project in my own Midlet. But I encountered a problem. The “Location” StringItem won’t return me the coordinate’s place name. Instead it gives me an error that reads “602: Address cannot be found”. Please help….

here’s the full code:

I tried this code in Nokia E 71 mobile, it’s working fine for showing the coordinates, but it could not represent the location info.

Could you please provide informatiom.

Thanks,

Is it possible to also display the location with maps (Google Maps, etc) on a J2ME application? If so, how?
